Application filed November 1, 1918. Serial No. 260,642.

To all whom it may concern:

Beit known-that I, GUY'L. WOODJARD, a citizen of the United-States,residing at San Diego, inthecountyof San Diego and State of California,have invented certain new and useful "Improvements in Spring-Oilers, ofwhich the following-is a specification.

My invention .relates'to a device for lubricating springs for vehiclesand the like and the objects of my invention are primarily improvementsover spring oilers as set'forth in my patentfor spring oiler No. 1,178,77 0 patented April=11, 19-16, and a later Patent No. 1,183,416patented May 16, 1916, and the objects of said improvements are-first,to provide a device of this class with an improved oil retainer in whichthe oil is confined a longer period of time, second, to providea meansfor redueingthe .quantity of feltused in the .oil'retainer, third toprovide a 11183118 130 be used; in connectionwith the-felt in the endfor -preventing the oil from seeping out at the ends, fourth to providea device of this class which is simple and economical of construction,durable, easy to install and which will not readily deteriorate or getout of order.

With these and other objects in view as will appear hereinafter myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed in detail and particularly set forth in the appended claims,reference being had to the accompanying drawings and to the charactersof reference thereon which form a part of this specification, in WhlCh-Figure 1 is a perspective view of the preferred form of the device shownmounted on a spring ready for use. Fig. 2 is a longitudinal sectionalview through the middle thereof. Fig. 3 is a transverse sectional viewthrough 3-3 of Fig. 2. Fig. 4: is a top view of the oil retainer portionof my oiler and Fig. 5 is a longitudinally sectional view of my oiler ina slightly modified form from that of the other views of the drawings.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings. The casing 1, pads 2 and3, glue members 4 and retaining shield 5 and oil hole cover 6 constitutethe principal parts of my oiler. The casing 1 consists of arectangularly shaped piece preferably metallic, provided with downwardlyextending right angled flanges 1 which are provided with inwardlyextending portions 1 along their lower edges. These portions 1 areadapted to fit into the usual slight grooves between the two upperspring leaves and hold the device in position on the upper spring leaf.The main portion is provided at each end withdownwardly extending edges1 as shown best in Figs. and 5-of the drawings, adapted to hold the oilretainer in position. It is provided with an oil hole 1 which is coveredon the inner side with a spring cover 6 which is secured to the casing 1preferably by a rivet 6". The shield 5 is rectangularly shaped with itssides 5 turned up a short distance and is of proper width to slidebetween the members I ofthe casing 1 and mounted in each end of thisshield 5 is a strip preferably of felt cemented transversely across saidpad inclosing the two ends. The outer edges of these strips are providedwith a glue sub stance whichprevents the oil from seeping out the endsof this retainer and also secures the strips to the shield 5, thusforming a reservoir between the strips 2 and 3 on the ends and theflanges 5 on the sides. It will be noted that the flanges 5 extend onlya little way and that these flanges fit closely against the sides of thecasing 1 so that this reservoir may be filled with oil and it will onlyseep out slowly between the flanges 5 of the members 1 on the casing 1.In the modified form of construction shown in Fig. 5 of the drawings,the structure is the same except that the shield 5 is omitted and thestrips 2 and 3 form the ends of the reservoir while the members 1 of thecasing 1 form the sides.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions I do not wish to be limited tothis particular construction, combination and arrangement but desire toinclude in the purview of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided asubstantial means for retaining the oil in the sides and ends which isvery essential but permits suflicient seepage for proper lubrication.That the glue strips 1 on the ends prevent leakage on the ends throughthe felt, that the flanges 5 retain a certain quantity of the lubricantwhich will gradually slop over the sides with the movement of thesprings when the vehicle is moving.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a spring oiler the combination of a casing provided with sidemembers adapted to fit over the upper leaf of the spring, a shield withupwardly flanged sides adapted to fit snugly against said side membersand a pad secured to said shield in each end thereof.

2. In a spring oiler the combination of a casing provided with sidemembers adapted to fit over the upper leaf of the spring, a shield withits sides flanged upwardly, adapted to fit snugly between said sidememhere, a pad secured to said shield in each end thereof, and a coat ofglue covering the outer surfaces of each of said strips.

3. In a spring oiler the combination of a casing provided with sidemembers adapted to spring over the upper leaf of a vehicle spring, aflat member with its sides flanged upwardly, adapted to rest on theupper leaf of the spring and its flanged sides fit snugly against saidside members and a pad secured to said shield in each end thereof,adapted to be compressed by said casing and seal the ends thereof.

4:. In a spring oiler the combination of a casing provided with sidemembers adapted to spring over the upper leaf of a vehicle spring, aflat member with its sides flanged upwardly, adapted to rest on theupper leaf of the spring and fitsnugly between said side members, a padsecured to said shield in each end thereof, adapted to be compressed bysaid casing and seal the ends thereof, and a coat of glue covering theouter surface of each of said pads.

5. In. a spring oiler the combination of a casing provided withdownwardly extending sides adapted to spring over the upper leaf of avehicle spring, a strip of felt mounted in each end of said casing ofsufficient thickness to be compressed by said casing and a coat of glueon the outer surface of each of said pads.

6. In a spring oiler the combination of a casing provided withdownwardly extending side members adapted to spring over the upper leafof a spring and an oil retarding receptacle with upwardly extendingsides and ends adapted to fit in said casing and rest on the top springleaf with its extending side members resting against the sides of saidcasing.

In testimony whereof, I have hereunto set my hand at San DiegoCalifornia this 26th day of October, 1918.
